ahm..is this picture at the beginning enough as credits? then i dont have to change it XD

and back to my question above, because of the event accures, i have read through the forum and have found a thread where they had the same question (without a solution) and they were all talking about setting flags. could that be a solution for me? what are that flags at scripting?

what i exactly need is: an event occurs, when another is finished or erased.
